Introduction: superficial dry needling is a common treatment for neck pain caused by miofascial trigger points. Objective: to investigate the effectiveness of the superficial dry needling of the active trigger point 1 of the upper trapezius compared with the needling of a 2 cm. distance point in subjects affected by neck pain. Material and method: Prospective, double-blinded, randomized-controlled pilot trial. Twenty-one students from Alcalá de Henares nursery degree with neck pain (mean age -S+ D: 21,8 +- 4,9). Inclusion criteria: neck pain with a duration of less than 6 months, active myofascial trigger point 1 of the upper trapezius and age between 18 and 38 years. Exclusion criteria: be afraid of acupuncture needles, be currently treated with acupuncture or dry needling, surgery in the neck/shoulder, suffer from blood coagulation disorders, skin injures or infections in the neck, pregnancy, rheumatological/neurological ill-nesses and take analgesic drugs during the study or one week before. Pain intensity, disability and pressure pain threshold is measured before, immediately after and a week after the intervention. The effectiveness of the treatment is evaluated using repeated-measurements ANOVA test (p < 0.05). Results: in superficial dry needling of the trigger point group the disability index (p = 0.024) and the pain intensity (p = 0.001) were significantly reduced immediately after the intervention. No significant differences were found between groups at pain intensity (p = 0.950) and disability index (p = 0.137) a week after the treatment, either at pressure pain threshold immediately or a week after. Conclusions: superficial dry needling at the active trigger point of the upper trapezius was an effective technique in-mediately after the intervention compared to the needling of a close point to decrease subjective neck pain and the neck disability index, but this effects don´t remained a week after.
